It only has one issue... when copying between its two SCSI disks 2 or more very large files (300MB+) at the same time.... it just "stops" only a power-reset helps...... but its seems like this is the SCSI driver, card, cable, termination, disks - chain that is having issues... As running at very high loads doesn't hurt little bruce

But getting it this far was quite a hell as i'd to try different 2.4.x kernels until this one was able to start both processors.. instead of starting one and crashing while starting the second... or panic-ing while booting etc....

And i agree with weeve on this:

Hypersparcs do work, however SMP is highly buggy. I run a dual 125 box with a non-SMP kernel and it works as fine as 2.4 or 2.6 does for sparc32.

Weeve, anything special you had to do for 2.6 to work stable?

Only real trick was getting the kernel small enough. If you use the new 2006.0 profiles with gcc-3.4.x, that should be a little easier as the compiled code is typically smaller in size than with gcc-3.3.x

I'm guessing they are not HyperSPARC CPU's

I've got two different SS20s, one with dual HyperSPARCs (ROSS 125 MHz) and dual SuperSPARCs (75MHz).
